The cylinder features a built-in, single-acting pump. Every unit includes a hardcoat-anodized aluminum cylinder and pump, valve, and stainless pump handle with two attachment options: 1) a roll pin, that when installed, locks the handle permanently, 2) the roll pin can be left off and the handle may be inserted when needed, but stored separately. Cylinders include a clevis pin on both ends. A fiberglass position indicator attached to the top clevis pin slides down the cylinder as it’s retracted for repeatable tension settings. Standard eye-jaw toggles fit all Harken cylinders and are recommended on all installations. The pressure-release knob turns clockwise to close and pump, counterclockwise to release. When closing the pump, the knob cannot be over-tightened by hand, preventing damage to the valve. Release speed depends on how far open the knob is turned. Pressure relief is factory set to prevent crew from over-tensioning the backstay. Harken integral backstay adjusters come in four sizes to fit boats 9 - 18 m (30 - 60') with stay diameters of 5 - 10 mm (7\/32 - 3\/8\").\u003c\/p\u003e\n\n\u003ch2 style=\"text-align: center;\"\u003e\n  \u003cspan style=\"font-size: 2x-large;\"\u003eTechnical Description\u003c\/span\u003e\n\u003c\/h2\u003e\n\n\u003ctable style=\"width: 100.059%;\" width=\"100%\"\u003e\n  \u003ctbody\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eWeight (kg)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e3.79 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eWeight (lb)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e8.36 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eMaximum wire Ø (mm)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e5.5 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eMaximum wire Ø (in)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e7\/32 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e-6\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eStroke (mm)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e360 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eStroke (in)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e14.17 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003ePin center length (closed) (mm)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e762 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003ePin center length (closed) (in)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e30 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eGap\/pin Ø (mm)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e11.1 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eGap\/pin Ø (in)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e7\/16 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003ePull force (kg)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e1710 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n    \u003ctr\u003e\n      \u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003ePull force (lb)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"width: 50%;\"\u003e3770 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":54217039446388,"sku":"HRHCI006BCC","price":2238.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/HRHCI006BCC-1.jpg?v=1774863010","url":"https:\/\/velasailingsupply.com\/products\/harken-25-mm-6-single-acting-integral-backstay-cylinder-bore","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
